Abstract

Non-Uniform Rational B-Spline (NURBS) surfaces can be non-uniform and defined for any degree, but existing subdivision surfaces are either uniform or of fixed degree. The resulting incompatibility forms a barrier to the adoption of subdivision for Computer-Aided Design. In this talk I will discuss our work towards a superset of NURBS which can handle irregularities in the control mesh. We call this target NURBS -compatible subdivision, as the resulting scheme would be able to represent any existing NURBS patch exactly. I will outline our strategy, discuss work which is already complete, and look at the challenges which lie ahead.
